When an airplane is flying 200 mph at 5000-ft altitude in a standard atmosphere, the air velocity at a certain point on the wing is 273 mph relative to the airplane. (a) What suction pressure is developed on the wing at that point

Pressure =

Explanation:

The pressure is calculated by Bernoulli's equation.

Solving it for P2

Now inserting values

P1 = 0 as it is given that initial point is at atmospheric point.

d= density = 2.05 sl/ft3

Vi = 200 mph = 293.33 ft/s

Vf = 273 mph = 400.4 ft/s

Putting these values

Changing the units to pounds per square foot

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.

answer:

sure does
